Abstract

A gateway in in-vehicle network (IVN) is an indispensable component as a conversion device between different communication protocols. Due to meet more complex network for IVN, how to improving the performance of gateway is more important. In this paper, a high efficient of CAN/FlexRay gateway using hardware/software (HW/SW) co-design method is proposed which is implemented with Xilinx FPGA system. The CAN controller and FlexRay controller are designed by SW and HW, respectively. The interface of HW and SW are used AXI-bus. The convert module is evaluated by a cost function. In addition, a transceiver PCB for connecting between the proposed gateway and external CAN/FlexRay-based ECUs is implemented. Experimental results show that the proposed gateway system can reduce at most 94.7% on execution time with related works which is more suited for IVN.

车载网络高性能CAN/FlexRay网关设计

网关作为不同通信协议之间的转换设备，是车载网络中不可缺少的重要组成部分。为了满足IVN日益复杂的网络需求，如何提高网关的性能显得尤为重要。本文提出了一种采用硬件/软件(HW/SW)协同设计方法的CAN/FlexRay网关，并在Xilinx FPGA系统上实现。CAN控制器和FlexRay控制器分别采用软件和硬件设计。硬件和软件接口采用axis总线。convert模块由成本函数求值。此外，还实现了一个收发器PCB，用于在所提出的网关和外部基于CAN/ flexray的ecu之间的连接。实验结果表明，该网关系统与相关工作相比，最多可减少94.7%的执行时间，更适合IVN。
